The 40mm Seiko Presage Craftsmanship Series SPB403 has been crafted in stainless steel with a super-hard coating, providing durability and resistance. The background of its dial is entirely white, giving it a highly sophisticated touch. Additionally, the double curvature of the sapphire crystal makes the piece appear much finer and more delicate on the wrist. Its bracelet is also made of stainless steel and features 5 links—two square-shaped at the ends and three rectangular and vertical in the center. This watch is the first model to feature the Caliber 6R55 movement, which has a power reserve that extends to 72 hours.
